Possible to create RAID setup using various external drives?

[Richie3000]

I've got a number of external drives, each at varying speeds and storage limits and am curious as to whether I can create a RAID setup if I were able to pull each drive out of it's enclosure?

If possible this would be a great way to add speed, convenience, and save some desk space.

Is this possible? If not, any ideas as to where I might find a good "Intro to RAID" guide to get started in the right direction?

Thanks!

No is my answer to your question.
Get a Hardware RAID chassis and put drives in it. Preferably the same drives AND drives that are supported by the chassis manufacturer.
If you don't do this then you risk two issues : a. One or both drives falling out of the array and being unusable. b. Continual resynching of the RAID array. Either one makes the RAID unusable.

See : http://pcguide.com/ref/hdd/perf/raid/index.htm for a guide.

What interface of external drive you have?
If you are using USB or FireWire, then you are not going to have much performance gain. The maximum FireWire 800 can deliver is around 85 MB/s and it is pretty much a single SATA drive can deliver.
What external HDD and machine you have?
